Great Set
The speakers were very easy to connect with my TV and work as expected. The wireless subwoofer was already paired with the soundbar and works great, I love the extra thump. Overall a good value with very good performance.

Outstanding sound
This sound bar was bought to use with a Roku flat screen TV in our backyard. TV is not mounted and is moved depending on where we sit.
Price was important since it is used outside. Picked it up from Best Buy for $149. Watching football outside today and sound is loud and clear. Also bass is good for outside.
Very happy with choice and I will recommend this system to friends who do the same outback.

S2. Works occasionally
Its just OK when it works, woofer is too quiet. S2 turns off (usually by itself it may not turn on. It's been off for hours, and I am losing faith that it decide to work again. I will return to store for refund.

Best Home Theater Sound System on a Budget!!
I am soo stoked with this purchase! I bought this soundbar for my budget home theater room. Including this soundbar, I've managed to put together a pretty sweet home theater for right around $300 - 3600 lumens projecting a 150" image on an automatic electric screen, with this system providing the sound!! Because of the limitations of my projector, its being ran by AUX cord, and the output quality still far exceeds what I expected!! Not to mention, it was a breeze to set up, as it was plug n ' play with the AUX cord. I'd definitely recommend this soundbar to anyone - on a budget or not! And I'll continue to stick with Polk Audio for all my sound needs!!

I got this for a large master bedroom. It was really easy to set up. It is such a huge upgrade from my tv speakers. Movies sound great and have real punch. I would highly recommend

Great soundbar but has limitations
Bought this a few months ago, and the sound is actually impressive from a small and inexpensive unit. Works great with TVs that do not have the best sound quality built in. The subwoofer is awesome, with deep base and very compact to sit nicely on a bookshelf.
Once major problem is the very cheap remote that comes with it. It is really cheap and it is difficult to adjust any volume or other functions since you don't know if the keypads have done what was intended. A better remote would be a great upgrade to this system.

Issue when connceting via HDMI (ARC).
I'm having the EXACT same issue as Mets01. I currently have the Signa S2 Soundbar connected to my TV via the HDMI (ARC). The soundbar does not always turn on. Sometime it does; most time it doesn't. I called Samsung regarding this issue and their solution was to unplug my TV, wait 30 seconds and then plug it back in (Are you kidding me?). I was thinking that it might be a firmware issue and that Samsung needs to send out a fix. But now that I see that other people are having the EXACT same issue I now know it's the soundbar and not the TV. I probably will be returning this to Best Buy. I always trusted the Polk name/products. Not so much anymore.

do i connect both HDMI and optical cables?
A shopper on Dec 15, 2018
  Only one is required. HDMI ARC is preferred if your TV has a compatible input.
